The problem is Objectivism was actually an Ayn Rand personality cult more than anything else, so you can't really get a coherent and complete philosophy out of it. Rothbard goes into quite a bit of detail about it in The Sociology of the Ayn Rand Cult.

Some highlights:
"The philosophical rationale for keeping Rand cultists in blissful ignorance was the Randian theory of "not giving your sanction to the Enemy." Reading the Enemy (which, with a few carefully selected exceptions, meant all non- or anti-Randians) meant "giving him your moral sanction," which was strictly forbidden as irrational. In a few selected cases, limited exceptions were made for leading cult members who could prove that they had to read certain Enemy works in order to refute them."
"The psychological hold that the cult held on the members may be illustrated by the case of one girl, a certified top Randian, who experienced the misfortune of falling in love with an unworthy non-Randian. The leadership told the girl that if she persisted in her desire to marry the man, she would be instantly excommunicated. She did so nevertheless, and was promptly expelled. And yet, a year or so later, she told a friend that the Randians had been right, that she had indeed sinned and that they should have expelled her as unworthy of being a rational Randian."
This is not to say Rand didn't have any valid insights, but since Rand really believed that things she said were by definition rational since she was rational (and as a bonus, the only possible rational thing)... there's a lot of junk and cruft in there, so there's no real good reason to take the whole label.
Diana Hsieh interviews Dr. Doug McGuff about avoidable injuries and deaths.
He's an emergency room physician in South Carolina, so he's pretty much just talking about what he's seen-- different regions have different characteristic injuries.
He says that you're safest in the largest car you can afford, which raises some interesting ethical issues.
There's a fair amount about the risks of getting overfocused on getting something done. This adds tremendously to the hazards of using ladders.
Also, did you know trees can go sproing? One of hazards of chainsaws is that a good bit of energy might be stored in a twisted tree trunk. Don't just know your physics, apply it!
More generally, there are machines and situations (ATVs, chainsaws, airplanes, skiing, etc.) which tend to make people feel more competent than they are.
On the other hand, injuries from rock climbing and horseback riding are less common than you might think. I don't know why the ancestral environment didn't give people a reflexive distaste against diving into water. Perhaps people back then had too much sense to dive much.
One of the pieces of advice-- to get out of stressful relationships-- is too general. This is mostly a good idea, but from what I've read, leaving a violent relationship can lead to more risk of violence. It's still a good idea to leave, but it's important to leave cautiously.
Both McGuff and Hsieh are objectivists, so some of the discussion might be in mind-killer territory.
Edited to add: It's possible that objectivism would be better discussed under a new post. It's certain that there's a bunch of interesting material in the podcast, and avoidable accidents are worth discussing.
